Background:  The Federal Aviation Administration has received reports of smoke, fumes and/or electrical fire emitting from passenger compartment baggage bins. Investigation revealed that the incidents were due to the failure of the fluorescent light ballasts.

 

This Directive is intended to prevent fire in the passenger compartment resulting from failure of the fluorescent light ballasts in the cabin sidewalls.

Overview

The Civil Aviation Regulations 1998, specifically PART 39 - 107 CIVIL AVIATION SAFETY AUTHORITY SCHEDULE OF AIRWORTHINESS DIRECTIVES, was enacted by the Australian Government to ensure the safety of civil aviation. This legislation addresses the problem of electrical fires in passenger compartments caused by faulty fluorescent light ballasts. The policy objective of this Act is to enhance aviation safety by mandating stringent measures to prevent such incidents. The Airworthiness Directive AD/ELECT/72 concerning fluorescent light ballasts was introduced following reports of smoke, fumes, and electrical fires in baggage bins due to ballast failures. The requirement to inspect and replace specific fluorescent light ballasts aims to mitigate the risk of fire within the cabin, ensuring the safety of passengers and crew on various aircraft models, including the McDonnell Douglas and Boeing series aeroplanes.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 107 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, mandates the replacement of certain fluorescent light ballasts in specified aircraft models. This directive applies to Day-Ray Products, Inc cabin sidewall fluorescent light ballasts with the specific part numbers listed in the Act, which are installed in particular McDonnell Douglas and Boeing aircraft models. These include the DC-8, DC-9, DC-10, C-9 (military), KC-10 (military), 707, 727, and 737 series aeroplanes. The geographic reach of this Act is national, as it pertains to the Commonwealth of Australia and applies uniformly across all states and territories. The Act requires a one-time visual inspection to identify the affected ballasts, their removal, and replacement with ballasts manufactured by Bruce Industries, in accordance with specified service bulletins. Non-compliance with this directive is strictly enforced, with particular emphasis on the removal of any Day-Ray fluorescent light ballasts from the aircraft cabin sidewalls, effective from the date of the directive’s promulgation.

Key Provisions

The Civil Aviation Safety Authority (CASA) has issued an Airworthiness Directive (AD) under the Civil Aviation Regulations 1998 (Part 39, Section 107) concerning the replacement of certain fluorescent light ballasts in specific aircraft models to prevent potential fire hazards. The directive, AD/ELECT/72, applies to Day-Ray Products, Inc cabin sidewall fluorescent light ballasts with specific part numbers listed in the directive (Section 1). These part numbers are applicable to various McDonnell Douglas and Boeing aircraft models including DC-8, DC-9, DC-10, C-9, KC-10, 707, 727, and 737 series aeroplanes (Section 1). The main requirements of this directive include performing a visual inspection to determine the type of fluorescent light ballasts installed in the upper and lower cabin sidewall (Section 1). If any ballast with the specified part numbers is found during the inspection, it must be removed and replaced with a ballast manufactured by Bruce Industries, following the relevant service bulletin for the aircraft model (Section 2). The directive mandates that no Day-Ray fluorescent light ballast with the specified part numbers can be installed in the upper or lower cabin sidewall of any aeroplane (Section 3). Compliance with the directive must be achieved before 1 April 2000, before any further flight after the inspection, and as of the effective date of the directive, which is 22 April 1999 (Section 3). The directive is grounded on reports of smoke, fumes, and electrical fires emanating from passenger compartment baggage bins, traced back to failures in the fluorescent light ballasts (Background). Failure to comply with this Airworthiness Directive can result in serious safety hazards, potentially leading to electrical fires on board the aircraft, which can be catastrophic. Penalties for non-compliance are not explicitly stated in the directive, but they could include enforcement actions by CASA, which may lead to fines, operational restrictions, or other regulatory actions under the Civil Aviation Act 1988 and the Civil Aviation Regulations 1998. Non-compliance can also result in legal liability for damages if an incident occurs due to the failure of the specified fluorescent light ballasts.
